First Climbs: Ascending, Descending, and Working Position

Objective. Students will ascend a full-height utility training pole to a minimum of 25 feet, establish a hands-free working position using the body belt positioning lanyard, perform a simulated task with both hands, and descend without a gaff-out, meeting the NCCER Power Line Worker climbing performance standard.

Pole climbing is the foundational physical skill of the electrical lineworker trade. Before you touch energized equipment, you must be able to ascend and descend a full-height utility pole safely, establish a stable hands-free working position, and return to the ground without a gaff-out. This lesson gives you the knowledge you need before your first supervised climb.

Your Climbing PPE — Inspect Before You Climb

Never leave the ground without a complete PPE inspection. Your required climbing equipment for this lesson includes:

Climbers (gaffs/hooks): Inspect the gaff point for sharpness, cracks, and proper length. A dull or damaged gaff will not bite into the wood and is a direct cause of gaff-outs. Inspect the leg iron for cracks and the straps for cuts or fraying.
Body belt with positioning lanyard: Inspect the D-rings, stitching, and buckle for damage. The lanyard snap hook must close and lock positively. A body belt is a positioning device, not a fall-arrest device — it holds you in place at working height but does not arrest a free fall.
Hard hat: ANSI/ISEA Z89.1 Class E (Electrical). Inspect for cracks and check the suspension system.
Safety glasses or goggles: Flying wood chips and debris are a real hazard.
Leather gloves: Protect hands during climbing; remove only when the task requires it and you are secured with the lanyard.
Work boots with ankle support: Must be compatible with the climber strap system.

Inspect every item before every climb. Tag out and remove from service any defective piece of equipment.

The Gaff and Why Gaff-Outs Happen

The gaff is the sharp steel spike attached to the inside of your leg iron. It penetrates the pole wood and supports your weight. A gaff-out occurs when the gaff pulls free of the wood unexpectedly, causing you to slip. Gaff-outs are the leading cause of climbing injuries in training.

The three most common causes of gaff-outs are:

1. Incorrect gaff angle: The gaff must enter the pole at roughly a right angle to the surface. If you stand too close to the pole, the gaff skims the surface instead of penetrating.

2. Insufficient body lean: You must lean away from the pole with your hips pushed outward. This drives the gaff inward and downward into the wood. Hugging the pole reduces gaff pressure and sets up a gaff-out.

3. Rushing weight transfer: Move one gaff at a time. Shift your weight fully onto the stationary gaff before lifting the other foot.

Ascending Technique: Step by Step

Start at the base of the pole with both gaffs placed at roughly knee height, one on each side.

1. Establish your stance: Feet shoulder-width apart, body leaning back from the pole, arms extended and hands gripping the pole above shoulder height with your palms, not a death-grip.

2. Load the lower gaff: Put your weight on one leg, pressing the gaff firmly into the wood.

3. Raise the free leg: Swing the free leg upward approximately 12–18 inches and drive the gaff into the pole at a right angle. Do not stab — plant deliberately.

4. Shift weight: Transfer your body weight onto the newly placed upper gaff before moving anything else.

5. Repeat: Move the lower gaff upward. Maintain a smooth, rhythmic motion. Your hands slide up the pole just ahead of your feet — they guide and balance, not haul.

Keep your hips away from the pole throughout. If you feel your body drifting toward the pole, correct it immediately by pushing your hips back out.

Establishing the Hands-Free Working Position

At your target height, you will set your positioning lanyard to work hands-free. This is called "belting out" or "setting your belt."

1. Stop climbing and stabilize: Both gaffs are planted, weight is balanced.

2. Pass the lanyard around the pole: Reach around the pole and clip the snap hook to the D-ring on the opposite side of your body belt, or use the manufacturer's prescribed method for your lanyard style. The lanyard should be taut enough that you can lean back into it and feel firm support.

3. Test the position: Lean back gradually, allowing the lanyard to take your weight. Your gaffs remain in the wood and your hands are now free.

4. Perform the task: With both hands free, you can retrieve a tool, simulate a connection, or complete an assessment task.

5. Re-grip before moving: Before ascending or descending from the working position, remove the lanyard and re-establish your climbing grip.

Descending Technique

Descending is statistically more hazardous than ascending because fatigue increases and attention often drops.

1. Lower one gaff at a time, the same deliberate one-at-a-time discipline as ascending.

2. Keep hips pushed away from the pole — the same lean applies going down.

3. Slide hands downward as you lower each gaff; do not step below your hands.

4. As you approach the ground, slow down. More gaff-outs happen in the last 10 feet than anywhere else.

5. Step off cleanly when your feet are near ground level.

Ground Observer and Communication

Your instructor and your peer partner on the ground are watching your technique throughout. Two-way radios allow the instructor at mid-height on the adjacent pole to give you real-time feedback. Listen and respond calmly — do not rush a correction. If the ground observer calls "Stop," plant both gaffs, stabilize, and wait for instructions.

Emergency Response

A first-aid kit is on site. If a gaff-out results in a fall or injury, all climbing stops immediately. The site instructor initiates first-aid response. Do not move an injured person unless there is immediate danger to life. Review the site emergency action plan before climbing begins.

What the NCCER Performance Standard Requires

To meet the NCCER Power Line Worker climbing performance standard for this lesson, you must complete two consecutive ascent-and-descent cycles to 25 feet with zero gaff-outs and demonstrate a proper, stable, hands-free working position on both cycles. Your instructor scores each cycle pass or fail using a structured rubric. Additional supervised climbs are required before the next lesson if you do not meet the standard.

Key terms10

Gaff (spike)The hardened steel point attached to the inside of the climber leg iron that penetrates the pole wood to support the climber's weight.

Gaff-outAn uncontrolled slip caused by the gaff pulling free from the pole wood, typically due to incorrect angle, insufficient body lean, or premature weight transfer.

Body belt (positioning belt)A wide leather or synthetic belt worn around the waist with D-rings for attaching a positioning lanyard; classified as a positioning device, not fall-arrest equipment.

Positioning lanyardThe leather or synthetic strap connected to the body belt D-rings that wraps around the pole, allowing the climber to lean back and work hands-free at height.

Hands-free working positionThe stable at-height stance achieved when the positioning lanyard is set around the pole and loaded, freeing both hands to perform work tasks.

Leg iron (climber)The metal frame assembly that straps to the lower leg and boot, holding the gaff in position for climbing; also called hooks or climbers.

Body leanThe outward angle of the climber's hips and torso away from the pole, which directs gaff pressure inward into the wood and prevents gaff-outs.

Field observation sheetA structured form used by instructors and peer partners to record specific technique errors or correct behaviors observed during a training climb.

Positioning devicePersonal protective equipment, such as a body belt and lanyard, that supports a worker in a fixed position at height but is not rated to arrest a free fall.

Training pole yardA controlled outdoor facility with utility poles installed to full or greater-than-standard height specifically for practicing climbing and aerial work skills.

In class: Supervised first ascent sequence: with an instructor acting as ground observer and a second instructor at mid-height on a parallel pole, each student ascends to 15 feet, pauses on instruction, sets the positioning lanyard around the pole to achieve a hands-free working position, removes and replaces one hand tool from their body belt tool pouch, then ascends to 25 feet and repeats the working-position sequence—ground observer records technique errors on a field observation sheet. · Paired observation and feedback: while one student climbs, a partner on the ground uses the technique cue card to watch for gaff angle, body lean, and smooth weight transfer and records observations; after descent both partners swap roles and then complete a 5-minute structured debrief comparing the field observation sheet to self-assessment. · Progressive repetition climbs: each student completes a minimum of four full ascent-and-descent cycles during the lesson period, with the instructor progressively withdrawing verbal cues after the second climb so students self-monitor; each cycle is logged in the climbing log (date, height reached, gaff-outs if any, equipment condition note).
Materials: Full-height OSHA-compliant training pole yard with poles set to 40-plus feet, safety observer vests, full climbing PPE set per student, tool pouches with sample lineworker hand tools, field observation sheets, climbing log books, two-way radios for ground-to-height communication, first-aid kit on site
Check: Each student must complete two consecutive ascent-and-descent cycles to 25 feet with zero gaff-outs and a proper hands-free working position on both cycles, scored by the instructor on a pass/fail performance rubric; students who gaff out on either cycle repeat additional supervised climbs before the next lesson begins.
